[Linphone-developers] videodisplay fails(Segmentation fault)

[Atom Chan]

Hi,

I used Fedora 12(2.6.31.6-166.fc12.i686), and I tried to study the Mediastreamer2 only(not linphone3).

First, I have yum install speex-devel SDL-devel libtheora-devel and ffmpeg-devel-0.5-5.20091026svn.fc12.i686.

Then I have install ortp-0.16.1.tar.gz and mediastreamer-2.3.0.tar.gz too.
During the installation, there were no errors.

My camera is Logitech QuickCam Express, I didn't install sepicial driver for it, I launched Cheese and it works, but not very fine.

I launched mediastreamer-2.3.0/tests/videodisplay, however the program crashed.
Please help me to see what's the problem.

I also attach the output of gdb.
